Custom Browser Gestures

Description

**This update keeps the progress bar visible while in fullscreen mode.** This patch enables 12 configurable gesture areas. You can reconfigure the action for each gesture in Tweaks. The gestures activate by swiping in from the screen edges. Current supported actions: Back, Forward, New Card, Toggle Fullscreen, Toggle Action Bar, Bookmarks, History, Refresh, Disable. Gestures assigned to the top of the screen will only activate in fullscreen mode. A visual overlay option highlights each gesture quadrant.
